• 控件重绘


    1. 设置控件DrawMode属性为OwnerDrawFixed,编辑控件DrawItem事件

    重绘tabControl——选项卡控件

        string text = ((TabControl)sender).TabPages[e.Index].Text;
        SolidBrush brush = new SolidBrush(Color.Black);
        StringFormat sf = new StringFormat(StringFormatFlags.DirectionRightToLeft);
        sf.LineAlignment = StringAlignment.Center;
        sf.Alignment = StringAlignment.Center;
        e.Graphics.DrawString(text, SystemInformation.MenuFont, brush, e.Bounds, sf);

    重绘listBox控件(注意修改涉及控件名的地方)

        e.DrawBackground();
        e.DrawFocusRectangle();

        //让文字位于Item的中间
        float difH = (e.Bounds.Height - e.Font.Height) / 2;    //字体垂直方向居中
        RectangleF rf = new RectangleF(e.Bounds.X, e.Bounds.Y + difH, e.Bounds.Width, e.Font.Height);
        e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), e.Font, new SolidBrush(e.ForeColor), rf);
